I bought a used 2010 Lifan LF50QGY, and I wanna track down a few cosmetic parts after I accidentally... rode it hard. Anyone have experience ordering from retrobikes.com or another site that actually carries Lifan parts? Also, the bike is listed as a 3-speed semi-auto, but I swear I'm shifting into a fourth gear while riding. Could it be mislabeled or is that common with these small displacement bikes?
